In the drawings, the thickness or size of each layer is exaggerated, omitted, or schematically illustrated for convenience and clarity of description. In addition, the size of each component does not necessarily reflect the actual size.

Hereinafter, a lighting apparatus according to an embodiment will be described in detail with reference to the accompanying drawings.

1 is a view illustrating a lighting apparatus according to an embodiment, and FIG. 2 is a perspective view of the lighting apparatus according to the embodiment. 3 is a view illustrating a lighting apparatus according to another embodiment. 4 is a diagram illustrating an adapter in the lighting apparatus according to the embodiment.

First, referring to FIGS. 1 and 2, in the lighting apparatus according to the embodiment, power terminals 22 are formed at both ends of the substrate 23 and a plurality of LEDs 21 are installed on the upper surface of the substrate 23. The light emitting device illumination unit 20, and the adapter 30 is coupled to both sides of the light emitting device illumination unit 20. In addition, a cover 40 for protecting the LED 21 may be further provided on the substrate 23.

In the light emitting device illumination unit 20, a plurality of LEDs 21 are arranged on the substrate 23.

The substrate 23 may be a printed circuit board (PCB) substrate on which a circuit pattern for providing power to the LED 21 is formed. In addition, the substrate 23 may be a substrate in which wiring for providing power to the LED 21 is provided on a plastic material.

In addition, a reflective coating layer (not shown) may be formed on the surface of the substrate 23, and coating silver (Ag) or aluminum (Al) may increase the efficiency of light emitted from the LED 21. .

The plurality of LEDs 21 may include LEDs emitting red, blue, and green colors, and may include LEDs emitting white light.

The cover 40 may be formed of a transparent plastic material, and may be formed of a plastic having various colors such as red, green, and blue as necessary. In addition, the cover 40 may be formed of a translucent material, in which case it may provide a soft atmosphere of illumination.

Power terminals 22 electrically connected to the adapter 30 are installed at both ends of the substrate 23 to provide power to the LED 21 from the outside.

The adapter 30 has a connection terminal 31 is inserted into the socket 11 for installing a conventional fluorescent lamp on one side, the power supply terminal 22 is inserted into the power supply terminal 22 of the light emitting device lighting unit 20 on the other side The terminal groove 32 is formed.

In the lighting apparatus according to the embodiment, the light emitting device lighting unit 20 and the adapter 30 may be coupled to each other, and thus may be installed in a socket 11 in which a fluorescent lamp is installed. Therefore, the lighting apparatus according to the embodiment in which the LED is used can be used without replacing the power supply including the socket 11 in which the fluorescent lamp is conventionally installed.

In particular, since the light emitting device illumination unit 20 and the adapter 30 are detachably installed, when a failure occurs in the light emitting device illumination unit 20 or the adapter 30, the light emitting device in which the failure occurs Since only the lighting unit 20 or the adapter 30 can be replaced, the maintenance cost is low.

In addition, since the light emitting device lighting unit 20 and the adapter 30 is detachably installed, the light emitting device lighting unit 20 and the adapter 30 may be replaced by only replacing the light emitting device lighting unit 20.

Referring to FIG. 3, unlike the lighting apparatus illustrated in FIGS. 1 and 2, the lighting apparatus illustrated in FIG. 3 includes a plurality of OLEDs 26 installed in the light emitting device illumination unit 20 instead of the plurality of LEDs 21. . The rest of the configuration is the same as described with reference to FIGS. 1 and 2.

Referring to FIG. 4, the adapter 30 includes an AC-DC converter 33, a regulator 34, and a light emitting device driver 35. The AC-DC converter 33 converts the AC power supplied through the socket 11 into DC power, and the regulator 34 has a constant DC power output from the AC-DC converter 33. The light emitting device driver 35 may convert the direct current voltage supplied from the regulator 34 into a driving pulse suitable for driving the plurality of LEDs 21 or the plurality of OLEDs 26. Output For example, as shown in FIG. 5, the adapter 30 includes a bridge rectifying circuit 33a and a smoothing circuit 34a so that a constant DC voltage can be output.

Therefore, the light emitting device illumination unit 20 is powered by an adapter 30 including the AC-DC converter 33, the regulator 34, and the light emitting device driver 35 to supply an AC power. It can also be used in the feeder.

That is, as shown in Figure 1, the power supply for fluorescent lamps includes a ballast 10 for converting commercial power into high frequency alternating current of 20 ~ 50kHz, and two sockets 11 connected to the ballast 10 However, since only a high frequency AC current is provided through the socket 11, the light emitting device lighting unit 20 may not be directly installed in the existing power supply device.

However, the lighting apparatus according to the embodiment may use the light emitting device illumination unit 20 while using the existing power supply as it is by installing the adapter 30.

In addition, since the adapter 30 and the light emitting device lighting unit 20 are detachable, the adapter 30 and the light emitting device lighting unit 20 may be installed where a power supply device for the light emitting device lighting unit 20 is installed. Separation has the advantage that can be used by connecting only the light emitting device illumination unit 20.

In FIG. 6, since the substrate 23 is formed in a semicircle shape, and the LED 21 is installed in a curved portion, the light emitting device illumination unit 20 is used in an environment in which it is effective to provide illumination only in a downward direction. For example, when the light emitting device lighting unit 20 is installed at a place such as a ceiling, the light efficiency may be increased.

Referring to FIG. 7, the light emitting device illumination unit 20 includes a substrate 23 having a circular cross section and a plurality of LEDs 21 installed on a circular surface of the substrate 23. Power supply terminals 22 are provided at both ends of 23.

In FIG. 7, since the substrate 23 is formed in a circular shape, and the LED 21 is installed in a curved portion, the light emitting device illumination unit 20 is used in an environment in which it is effective to provide illumination in a 360 degree direction. For example, when the light emitting device lighting unit 20 is installed in a cylindrical advertising facility, the light efficiency may be increased. Of course, the light emitting device lighting unit 20 shown in FIG. 7 may be used as lighting for home or office.

Referring to FIG. 8, the light emitting device illumination unit 20 includes a substrate 23 having a circular cross section, and a plurality of LEDs 21 installed on a circular surface of the substrate 23. Power supply terminals 22 are provided at both ends of 23. In addition, a cover 40 for protecting the LED 21 is further included.
